The Shape of Colour

Released in 2015, The Shape of Colour represents a pivotal moment for Intervals, as Aaron Marshall returned the project to a purely instrumental format following the vocal-led 'A Voice Within'. This shift allowed Marshall to fully explore his 'guitar-as-vocalist' philosophy, resulting in some of the most melodic and accessible progressive metal of the decade. The album is notable for its departure from the darker, more aggressive tropes of the djent movement, opting instead for a fusion-influenced sound that incorporates elements of jazz and pop. Recorded with a powerhouse rhythm section including Cameron McLellan and Travis Orbin, the technicality is immense but always serves the song. Critics praised the record for its 'fresh' perspective on instrumental music and its ability to maintain listener interest through superior phrasing and shorter, punchier track lengths. It remains a cornerstone of the 'bright' progressive metal subgenre.
